Wind-to-Hydrogen Tech Goes to Sea

Cars That Think

Airplanes, for example, won’t be able to fly long distances on battery power. In addition, for many uses, energy can’t be used the instant it’s generated but must be stored for hours or days and transferred across continents or even oceans, neither of which is currently economically or technologically feasible.
